WEIGH TO GO! MASTERCHEF IS BIGGEST LOSER!

There’s plenty of room in “MasterChef” Graham Elliot’s kitchen these days – the TV culinary champ has dropped an amazing 150 pounds in nine months!

The 6-foot-2 cooking superstar, who owns two of Chicago’s hottest restaurants, tipped the scales at a whopping 405 pounds just a year ago. Today, the dad of three is down to 255.

“This is what I need to do for my family,” said Graham, 37. “What’s going to make me healthy is the most important thing right now so I can enjoy my kids and be around long enough to see them grow up.

“It wasn’t just how I looked. Being healthy for my family was the trigger.”

Graham stars alongside top chef Gordon Ramsay and restaurateur Joe Bastianich on “MasterChef,” a FOX reality show in which amateur cooks compete for a chance to win a cash prize and the MasterChef title.

He underwent a radical sleeve gastrectomy at the University of Chicago Medical Center, which left his stomach a quarter of its original size.

Graham chose this procedure over other options, noting: “With gastric bypass and other surgeries, there are some ingredients you can’t eat because it will cause you to get sick. This procedure will allow me to still taste and try everything.”

He’s also stopped eating sweets and works out every other day, running up to five miles. Now, Graham has his sights set on the Oct. 12 Chicago Marathon, which he hopes to run with his “MasterChef” cohorts, Gordon and Joe.
